PAVEMENT EVALUATION AND OVERLAY DESIGN: A METHOD THAT COMBINES LAYERED-ELASTIC THEORY AND VIBRATORY NONDESTRUCTIVE TESTING

A procedure has been developed for the determination of the load-carrying capacity and required overlay thickness of airport pavements. The procedure combines a layered-elastic theoretical approach and vibratory nondestructive testing to determine the value of the Young's modulus of the subgrade. A computer program SUBE is used to determine the value of the Young's modulus of the subgrade from the measured dynamic response of a pavement. A computer program PAVEVAL is used to calculate the load-carrying capacity and required overlay thickness in terms of the structure of the pavement and subgrade and in terms of limiting strain and stress conditions. The procedure was evaluated by calculating the load-carrying capacity and overlay thicknesses for single-wheel and multiple-wheel loadings on rigid and flexible pavements. /Author/
